A nonlinear error control method for a five-axis machine tool, relating to the field of precision machining technology, is disclosed. The method involves setting a nonlinear error threshold; deriving forward and inverse kinematics based on the machine tool structure; acquiring tool position information at the beginning and end of the toolpath, calculating the corresponding movement of each axis, setting the starting point, deceleration times, and desired feed rate; calculating the fine interpolation points between the two axes; calculating the nonlinear error; if the error is not specified, then setting the feed rate and recalculating; if the error is not specified, then updating the speed between the two axes, setting the feed rate, and resetting the feed rate. This process is repeated until the end of the operation. For five-axis machine tools with RTCP functionality, by setting an error threshold, adjusting the machining speed between tool positions, and controlling the number and distance between interpolation points, the nonlinear error can be effectively controlled while ensuring machining efficiency.
